The new update allows you to pay to replay and screenshot short snaps.
However, the self-destructing nature of the pictures is what makes the app
so popular

Snapchat has been causing quite a stir with its new update, with new filters that make you look like you have hearts for eyes, or like you're vomiting rainbows.

However, their less flashy new feature is perhaps more interesting - they are letting you pay to replay 'snaps' - pictures that last for a few seconds then immediately self-destruct - and screenshot them.

Snapchat is immensely popular for sexting, because you can send a naked photograph of yourself to your beau and rest assured that it won't end up on Facebook, as it self destructs in a matter of seconds.

The rise of Snapchat porn

The majority of Snapchat users are quite young, teenagers and people in their early twenties. It isn't inconceivable that someone could use the apparent non-permanent nature of the platform to coax another person into sending them - then paying to replay and screenshot the picture.

Sadly, people aren't always trustworthy with pictures you send to them. Some advice: if you wouldn't text a picture of yourself naked to this person because of security worries, don't send it on Snapchat.
